The Telemecanique XT218A1FAL2 is a capacitive proximity sensor from the XT2 series with a cylindrical M18 threaded (M18 × 1) plastic body. According to the manufacturer it detects insulated or conductive materials. It is non-flush mountable; the nominal sensing distance is 8 mm and the assured operating distance (Sa) is 0–5.8 mm. The sensing distance is set with the potentiometer on the body within an adjustment zone of 0–12 mm. The output is a 2-wire AC type operating as normally open (1 NO); the supply is 24–240 V AC, 50–60 Hz.

Supply voltage limits are 20–265 V AC. The switching frequency reaches 25 Hz; the maximum switching current is 300 mA, the voltage drop in the closed state is below 10 V and current consumption is below 4 mA. The first-up delay is 200 ms. Connection is by a 2 m PVC cable, and a yellow LED shows the output state. The degree of protection is IP67 (double insulation, IEC 60529) and the operating temperature range is -10 °C to +60 °C. The fixing nut tightening torque is 3 N.m.
